We present a discussion on how an area-encoded fringe pattern is applied to describe the 3D shape of objects that have spatially isolated surfaces. Phases of the fringes can be carried out without ambiguity to retrieve the 3D shape. Compared with conventional fringe projection techniques, the proposed scheme is relatively reliable and robust to identify the fringe order. Only one phase measurement is required. This makes it possible to analyze dynamic objects.
